Farah adds that the recent release of Akshay-Sonakshi Sinha-starrer Rowdy Rathore is the primary reason behind Akshay's no-show.
"We have just seen a lot of them doing Rowdy Rathore promotion, we didn't want our film to look the same. It's a very different film, it's a kids-friendly film. Our USP are the aliens and we want to play upon that," Farah said.
Meanwhile, Farah is happy to have produced a film like Joker and said: "It's for kids. After a very long time you'll see a film where parents can take their kids and they don't have to worry that something will come now, a kiss or sex or violence. It's very clean and entertaining film," Farah said.
Joker also stars Sonakshi Sinha, Shreyas Talpade and Minissha Lamba and hits theatres Aug 31.
